Ring 19 also has a tapered portion 21 adapt-. ed to engage the packing ring 12 and to bind it on the flared end or shoulder 11 so as to press said ring 12 against the pipe 17, there by to seal the joint between said pipe and the flue 8. Lugs or projections 22 are formed on or secured to the ring 19 and by means thereof said ring can be shifted upwardly along the pipe 17 thus to permit convenient renewal of the packing rings.

The pipe 17 is adapted to be supported in any suitable manner above the opening 2, suflicient clearance space being left to allow cars to pass thereunder to deliver coal to the oven or to allow for the discharge of coal from suitable elevators. If desired this pipe 17 can"op'eii into a main from which a number of pipes depend above a series or battery of ovens. Ring 3- can be placed in the opening 2 without seriously interfering with the operation of the oven and after it has thus been positioned and the pipe 17 has been mounted above the opening, the flue 8 can be lowered so as to cause the lower edge of the hood 6 to rest snugly in the groove 5. Clay such as indicated at 23 can then be placed in the groove 5. and along the outer side of the hood so as to seal the joint and the weights 18 can be detached from the cables 14. The apparatus is now in condition for use and as the coal in the oven is heated the generated gases will flow upwardly through the opening 2 ,and the hood 7 into flue 8 and pipe 17 and can then be conducted to the point of use. Should the generation of the gases be too rapid, the excessive pressure of the gases against the hood 7 will cause the hood to lift off of the ring 3, flue 8, at this time, sliding upwardly along the pipe 17. Thus the surplus pressure will be released and injury to the oven will be prevented. When it is desiredto lift the attachment so as to allow the oven to be charged, the weights 18 are attached to the cables and the hood 7 can then be thrust upwardly until sufficient clearance has been provided to allow the cars or other supplying means to pass into position over the opening 2. Obviously when the flue 8 is raised the ring 19 and the packing 12 and 13 will shift therewith along the pipe 17 The packing can be renewed whenever desired simply by lifting the ring 19 relative to the flue 8, whereupon new packing rings can be placed in position and when the ring 19 is released it will gravitate onto said rings and compress them so as to completely seal the joint.

By providing a gas collecting apparatus such as described,the gases which are generated in bee-hive ovens and ovens of other construction and which gases have heretofore been wasted, can be collected and utilized at slight additional cost over and above the cost of the ovens. Furthermore, an atsiderable length of time nor does it interfere with the ordinary means employed for charging the oven. 7

As an additional means for preventing leakage of gas at the joint between the pipe and the slidable flue, the ring 19 maybe flared at its upper end as shown at 19', thus to receive an additional packing.

It will be noted that the groove 5 in which the lower edge of the hood 6 rests is of considerable width as compared with the thickness of thehood. This is provided in order that the hood may be free to expand and contract while seated in the groove.

What is claimed is 1. The combination with a coke oven having a feed opening in the top thereof, of means for conducting gases from the oven, said means including a gas conducting pipe supported above and in line with the opening, and a hood removably mounted on the oven and around the opening and below and communicating with the pipe, said pipe and hood being concentric with the axis of the opening.

2. The combination with a coke oven having a feed opening in the top thereof, of gas collecting means including a gas con ducting pipe supported above and in line with the opening, a base member upon the oven and surrounding the opening, and a flue supported by said base member and below' and communicating with the pipe, said flue being movablymounted, said pipe and flue being concentric with theaxis of the opening.

3. The combination with a coke oven having a feed opening in the top thereof, of means for collecting gas from the opening, including a gas conducting pipe overhanging the opening, a base member upon the oven and surrounding the opening, and a flue slidably mounted on said pipe and normally seated at its lower end upon said base member, said flue and pipe being concentric with the axis of the opening.

4. The combination with a coke oven having a feed opening in the top thereof, of means forcollecting gas from the opening, including a gas conducting pipe overhanging the opening, a base member upon the oven and surrounding the opening, a flue slidably mounted on said pipe and normally seated at its lower end upon said base memher, and means for sealing the joint between the pipe and flue, said flue and pipe being concentric with the axis of the opening.

5. The combination with a coke oven having a feed opening in the top thereof, of means for collecting gas generated in the oven, said means including a gas conducting pipe supported above the pipe supported above the opening, a flue slidably mounted on said pipe and normally supported at its lower end by the oven, the lower end ,of said flue surrounding the opening, said flue having an inwardly extending portion for receiving pressure from generated gases.

6. The combination'with a coke oven having a feed opening in the top thereof, of means for collecting gas generated in the oven, said means including'a gas conducting opening, a flue slidably mounted on said pipe and normally supported at its lower end by the oven, the lower end of said flue surrounding the opening, said flue having an inwardly extending portion for receiving pressure from generated gases, and means for sealing the joint between the oven and the lower end of the flue.

7 The combination with a coke oven having a feed opening in the top thereof, of means for collecting generated gases, including a gas conducting pipe supported above the opening, a flue slidably mounted on said pipe and having an enlargement at its lower end surrounding the opening and resting on the oven, and means for sealing the joint between said enlarged end of the flue and the oven.

8. The combination with a coke oven having a feed opening in the top thereof, of means for collecting generated gases, including a gas conducting pipe supported above the opening, a flue slidably mounted on said pipe and having an enlargement at its lower end surrounding the opening and resting on the oven, means for sealing the joint between said enlarged end of the flue and the oven, and a counter balance for the flue, said flue and pipe being concentric with the axis of the opening.

. 9. The combination with a coke oven having a feed opening in the top thereof, of means for collecting generated gases, including a gas conducting pipe supported above the opening, a flue slidably mounted on said pipe, the lower end of said flue being adapted to rest upon the oven and to surround said opening, a packing ring extending around the pipe and supported by the flue, and a ring weight loosely mounted on the pipe and bearing on said packing ring to seal the joint between the pipe and flue.

1.0. The combination with an oven having a feed opening in the top thereof, of means for collecting generated gases, including a gas conducting pipe supported above the opening, a flue slidably mounted on said pipe, the lower end of the flue being adapted to rest on the oven and to extend around the opening, the upper end of the flue being flared, there being an annular shoulder upon the upper portion of said flue, packing rings upon the shoulder and flared end respectively of the flue, and a ring weight resting upon said rings to seal the joint between the ring and flue and between the flue and pipe.

11. The combination with a coke oven having a feed opening in the top thereof, of a gas collecting attachment including a ring insertible into the opening and having a grooved annular flange constituting a seat, a gas collecting pipe supported above the opening, a flue slidably mounted on the pipe and bearing at its lower end within the groove, means for sealing the joint between said flange and the flue.
